Generate Range Rate measurement Error

Postby jlin » Wed May 02, 2018 4:36 pm

I'm attempting to run the example to generate measurement for Doppler range rate, I've modified the example that came with GMAT 2017 and was able to successfully generate range rate (one way) just fine when I'm using the transmitter frequency at 7000 Hz. But when I increase to anything greater than 8000 as well as 27000 Hz I get an error thrown by GMAT says "Measurement Exception Thrown: Error in PhysicalMeasurement::FrequencyBand(): GMAT cannot specify frequency band for frequency = xxxxx Hz".

Am I missing something? Do I need to change something else besides the the transmitter frequency? Thanks.

As a follow up question, when trying to generate Range Rate the third column of the field is output as: 9010. However, in the document it says the observation type index should be 9012? This is an error in the document? I also tried to change the output GMD to 9012 (instead of the 9010) and the estimate won't work at all. Is this an issue?
